Docker and Docker Compose¶
You will need the following installed on the platform on which you will be operating, or developing on (or for), Hyperledger Fabric:
You can check the version of Docker you have installed with the following command from a terminal prompt:
Installing Docker for Mac or Windows, or Docker Toolbox will also install Docker Compose. If you already had Docker installed, you should check that you have Docker Compose version 1.14.0 or greater installed. If not, we recommend that you install a more recent version of Docker.
You can check the version of Docker Compose you have installed with the following command from a terminal prompt:
Go Programming Language¶
Hyperledger Fabric uses the Go programming language 1.9.x for many of its components.
Building with Go version 1.8.x is not supported
- Go - version 1.9.x
Given that we will be writing chaincode programs in Go, there are two
environment variables you will need to set properly; you can make these
settings permanent by placing them in the appropriate startup file, such
as your personal
~/.bashrc file if you are using the
First, you must set the environment variable
GOPATH to point at the
Go workspace containing the downloaded Fabric code base, with something like:
You must set the GOPATH variable
Even though, in Linux, Go’s
GOPATH variable can be a colon-separated list
of directories, and will use a default value of
$HOME/go if it is unset,
the current Fabric build framework still requires you to set and export that
variable, and it must contain only the single directory name for your Go
workspace. (This restriction might be removed in a future release.)
Second, you should (again, in the appropriate startup file) extend your
command search path to include the Go
bin directory, such as the following
bash under Linux:
While this directory may not exist in a new Go workspace installation, it is populated later by the Fabric build system with a small number of Go executables used by other parts of the build system. So even if you currently have no such directory yet, extend your shell search path as above.
Node.js Runtime and NPM¶
If you will be developing applications for Hyperledger Fabric leveraging the Hyperledger Fabric SDK for Node.js, you will need to have version 8.9.x of Node.js installed.
Node.js version 9.x is not supported at this time.
- Node.js - version 8.9.x or greater
Installing Node.js will also install NPM, however it is recommended
that you confirm the version of NPM installed. You can upgrade
npm tool with the following command:
npm install firstname.lastname@example.org -g
The following applies to Ubuntu 16.04 users only.
By default Ubuntu 16.04 comes with Python 3.5.1 installed as the
The Fabric Node.js SDK requires an iteration of Python 2.7 in order for
operations to complete successfully. Retrieve the 2.7 version with the following command:
sudo apt-get install python
Check your version(s):
If you are developing on Windows 7, you will want to work within the Docker Quickstart Terminal which uses Git Bash and provides a better alternative to the built-in Windows shell.
However experience has shown this to be a poor development environment
with limited functionality. It is suitable to run Docker based
scenarios, such as Getting Started, but you may have
difficulties with operations involving the
On Windows 10 you should use the native Docker distribution and you
may use the Windows PowerShell. However, for the Download Platform-specific Binaries
command to succeed you will still need to have the
available. You can get it as part of Git but beware that only the
64bit version is supported.
Before running any
git clone commands, run the following commands:
git config --global core.autocrlf false git config --global core.longpaths true
You can check the setting of these parameters with the following commands:
git config --get core.autocrlf git config --get core.longpaths
These need to be
curl command that comes with Git and Docker Toolbox is old and
does not handle properly the redirect used in
Getting Started. Make sure you install and use a newer version
from the cURL downloads page
For Node.js you also need the necessary Visual Studio C++ Build Tools which are freely available and can be installed with the following command:
npm install --global windows-build-tools
See the NPM windows-build-tools page for more details.
Once this is done, you should also install the NPM GRPC module with the following command:
npm install --global grpc
Your environment should now be ready to go through the Getting Started samples and tutorials.
